A "personal drone" burst into flames Tuesday afternoon, sparking a wildfire that quickly grew to more than 300 acres in northern Arizona, officials said.

The Kendrick Fire, southeast of Kendrick Park and northwest of Flagstaff, started about 12:35 p.m. and quickly blackened about 335 acres of grass before crews stopped its spread, Coconino National Forest spokesman George Jozens said.

About 30 firefighters from the U.S. Forest Service and Summit Fire and Medical worked to quell the fire. They set fires around Chapel of the Holy Dove on U.S. Highway 180, slowing the first uncontrolled spread.

Jozens said the area has received moisture through the winter months, but light, flashy fuels such as grass remain extremely flammable. He encouraged anyone working with battery-operated or potentially flammable devices to have a fire extinguisher within reach — just in case.

"Please make sure that your fire is safe," he said.

Additional details about the type of drone were not immediately available.
